         4 . The energy saving method according to  claim 1 , further comprising:
 the processor determining whether a total power value being consumed by the servers is greater than a first power value;   determining whether the server is in the first state when the value of total power being consumed by the servers is greater than the first power value;   determining whether a length of time for which the server being in the first state reaches a preset time if the server is in the first state; and   controlling the server in the first state to enter the second state if the time when the server is in the first state reaches the preset time.   
     
     
         5 . The energy saving method according to  claim 4 , further comprising:
 determining whether the total power value being consumed by the servers is less than or equal to a second power value if the total power value being consumed by the servers is less than the first power value; and   controlling the server in the second state to enter the first state if the total power value being consumed by the servers is less than the second power value.   
     
     
         6 . The energy saving method according to  claim 1 , wherein the first state is a standby state, and the second state is a shutdown state. 
     
     
         7 . The energy saving method according to  claim 1 , wherein the operating parameters comprise power, IP address, host name list, power status, and system usage of each server. 
     
     
         8 . The energy saving method according to  claim 7 , wherein the system usage comprises CPU utilization, available storage device value, disk utilization, and rate of the network sending or receiving data. 
     
     
         9 . The energy saving method according to  claim 8 , wherein when the CPU utilization of the server is less than 10%, the available storage device value is greater than 90%, the disk utilization is less than 10%, and the rate of the network sending or receiving data is less than 10MB/s, the processor determines the server is in the first state. 
     
     
         10 . The energy saving method according to  claim 1 , wherein the preset time is 12 hours. 
     
     
         11 . An energy saving device communicating with a plurality of servers and comprising:
 a storage device; and a processor;   wherein the storage device stores one or more programs, which when executed by the processor, cause the processor to:
 obtain operating parameters of the servers; 
 determine whether the server is in a first state according to the operating parameters; 
 control the server in the first state to enter a second state; 
 determine whether a length of time for which the server being in the first state reaches a preset time; 
 control the server in the first state to enter the second state if the time when the server is in the first state reaches the preset time; and obtain the operating parameters of the servers again if the time when the server is in the first state does not reach the preset time. 
   
     
     
         12 . (canceled) 
     
     
         13 . The energy saving device according to  claim 11 , wherein the processor is further caused to:
 output prompt information to a user when the server in the first state enters the second state.   
     
     
         14 . The energy saving device according to  claim 11 , wherein the processor is further caused to:
 determine whether a total power value being consumed by the servers is greater than a first power value;   determine whether the server is in the first state when the total power value being consumed by the servers is greater than the first power value;   determine whether a length of time for which the server being in the first state reaches a preset time if the server is in the first state; and   control the server in the first state to enter the second state if the time when the server is in the first state reaches the preset time.   
     
     
         15 . The energy saving device according to  claim 14 , wherein the processor is further caused to:
 determine whether the value of total power being consumed by the servers is less than or equal to a second power value if the total power value of the servers is less than the first power value; and   control the server in the second state to enter the first state if the total power value of the servers is less than the second power value.
